SpletPolymers are large molecules formed by covalently linking many small monomers into long chains. Polyethylene, used to make plastic bottles and bags, is a synthetic polymer with molecular formula (-C 2 H 4-) n. The number of linked monomers (n) is very large in polyethylene and the molecular weight is around 5 million Daltons. SpletThe law is approximately valid for real gases at sufficiently low pressures and high temperatures. The specific number of molecules in one gram- mole of a substance, defined as the molecular weight in grams, is 6.02214076 × 10 23, a quantity called Avogadro’s number, or the Avogadro constant.
